With high running accuracy, high-speed performance and high system rigidity, super-precision bearings are ideal for machine tools and other precision applications such as rolling mills, racing cars and marine vessels. The bearings also minimize noise, vibration and heat generation.While all bearings are extremely precise mechanisms, a designer must consider the benefits of tighter tolerances in terms of performance and bearing life. For example, there is a direct correlation with precision class and bearing life.
